SPECPIC'ATON forming part of Letters Patent No. 378,000, datedPebruary`l4, 1888.

' Application led August 12, 1887. Serial No. 246,798. (No model.)

To all whom it may concern:

Be it known that I, FRANK F. GIBEoRD,-a citizen of the United States,residing at Englewood, in the count-ylof Cook and State of Illinois,have invented certain new and useful Improvements` inArtificial-Stone(Pavements; and I do declare the following to be a full,clear, and exact description of theinvention, such as will enable othersskilled in the art to which it -appertains to make and use the same,reference being had to the accompanying drawings, and to the letters andfigures of reference marked thereon, which form a partof thisspeciication. A

My invention has relation to` artificial-stone pavements; and the objectis to provide a simple, cheap, and durable pavement, of the'classdescribed, that will present a true surface for wear, and at the sametime obviate all tendency to cracks, separation at the joints, orirregularities in the surface; and to these ends Vthe novelty consistsin the construction of the same, as will be hereinafter more fullydescribed, and particularly pointed out' in the claim.

In the accompanying drawings, the same letters of reference indicatelike parts of the invention. l

Figure l is a top plan view of a sectionof my new' pavement. Fig. 2 is areverse or bot vtom plan View of the same, and Fig. 3 is a bottomperspective view of one of the blocks.

forming the pavement. 'Y

The pavement proper consists of a series of blocks, A, provided withintegral projections vI and recesses b, sadprojections and recessesbeing tlush with the bottom of the block and extending upyvard aboutone-half the thickness of the block.

The top surface of the blocks is a true square, and consequently thepavement may beextended indefinitely ,by simply alternating the sides ofthe blocks as they are 1aid-that is, so arranging them that a side witha projec` tion will be contiguous to a side with a-recess. It will beobserved that the projections are rectangular in form, While therecesses iare inward, so that when the pavement is setin a bed or layerof cement the cement 'will till up the interstices, and when it hardensor sets make it practically a solid sheet of pavement.

- The blocks may be pressed or molded of any style of concrete, cement,or'tiling `and 'then baked, and of course may be ornainented or coloredto suit the taste, and can thus be suited in their cheapest andplainest` form -to street- Walks, while the more elaborate are suitable,Y

for all styles of tiling for halls, vestibules, mantels, and the like.

What I claim is- I As a new article ofmannfacture, a block forpavements, having two of its sides pro- A vided with projections, andits two opposite sidesprovided with recesses, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
